Mary Lynn Rajskub‘s Chloe O’Brian wasn’t even introduced until the third season of 24, but she quickly established herself as a fan favorite and an integral part of the thriller series. The numbers bear that out, too. She appeared in 125 episodes of the show, more than any character not named Jack Bauer.

Put simply, it just isn’t 24 without Chloe — which is why fans should be thrilled to learn that she is, in fact, coming back for the limited sequel series 24: Live Another Day. More on Rajskub’s casting after the jump.

TheWrap reports that Rajskub is set to reprise her role for the series, joining star Kiefer Sutherland. Aside from the two actors, many of the original show’s writers and producers are also signed on to return.

In a statement, Rajskub expressed excitement at her return. “I am thrilled to be working with Howard [Gordon] and the writers again — and, of course, Kiefer,” she wrote. “There’s a lot more room to grow in my character… I’m going to start sharpening my computer skills right now.”

Despite her awkward (though brilliant) personality, Chloe developed a close, fiercely loyal friendship with Jack over the course of the series. As a CTU systems analyst, she frequently assisted Jack in the field from her station behind her desk, sometimes at the risk of her own life or career. Though she got her share of more hands-on badass moments as well — it turned out the desk jockey could be pretty handy with a weapon.

24: Live Another Day picks up several years after the final season of 24. While the limited series will follow the 24-hour format of earlier seasons, it’ll condense that day into just 12 episodes, highlighting the most eventful hours during that period. An exact premiere date hasn’t been announced, but it’s expected to it sometime in May 2014.

Outside of 24, Rajskub has had a string of guest-starring roles on shows like Arrested Development, New Girl, and Raising Hope over the past few years. On the big screen, her most recent appearances were in the indies Safety Not Guaranteed and The Kings of Summer.
